Giovanni Marchese opened the scoring for Catania just before the half-hour mark but Pablo Osvaldo equalised in the 59th minute with a stunning overhead kick.
And while the visitors edged ahead again ten minutes later when Alejandro Gomez found the back of the net, Nico Lopez ensured the Giallorossi would take home a share of the spoils by coolly firing home at the death.
Speaking after the game, Zeman expressed his delight at the number of fans that turned up to welcome him back to the Stadio Olimpico, and apologised for his inability to give them more the cheer about.
"It was great to be back at the Olimpico and I'm pleased that lots of people came to the stadium tonight [Sunday]," he said on the club's official website.
"I've always provided football 'for the people', to entertain them and make want to come and see football.
"I hope the people come to the stadium for that reason - to enjoy themselves."
However, Zeman's joy at returning to the Olimpico stadium was cut short after conceding two contentious goals.
"I'm bitter about the points we lost, mainly because the two goals we conceded were offside.
"I'm sorry about the result, we could have played better.
"We tried out different things in training and I don't know what it was today [Sunday] - whether we were nervous or afraid to lose the ball too much."
The Czech tactician also dismissed claims he would consider goalkeeper Maarten Stelekenburg's place in his starting XI and called for more from his wingers, although he felt both of goals they conceded were offside.
"Have I been unconvinced by Stekelenburg? I've never said that," Zeman added. "He's an excellent keeper. Our problem today [Sunday] was that the wide players didn't cut inside enough.
"I'm disappointed with with the points we've dropped, but I must that both goals we conceded were offside."
Catania boss Maran was making his Serie A debut as a coach having replaced Fiorentina-bound Vincenzo Montella in June.
He told Sky reporters after the game: "With regret, we leave with a draw.
"We played well at a difficult place. It's a shame about that goal at the death, but the end of the game was so intense that we were always vulnerable to errors."
Roma are next in action on Sunday when they take on Inter Milan at the Giuseppe Meazza.
